Fault Finding
Ensure the electrical supply to the unit is isolated before making any adjustments.
!
Load will not switch on
a) Unit is not powered
•
Ensure the unit is correctly connected to an active mains supply.
b) Load is not connected correctly
• Ensure the load is connected appropriately. The relay output is volt-free so must be
connected suitably to a supply in order to power a load.
• Check that the load works on its own by bypassing the detector.
c) Unit is not set up correctly
•
WMPAD3(-L)
Ensure the operating mode has been selected appropriately. In
Absence Mode
, the override button must be used to switch on the load.
• Wait 1 minute after connecting the mains supply for the PIR sensor to stabilise.
•
Ensure the
Lux Level
setting is appropriate (including for non-lighting loads).
• Ensure the unit is sited away from strong light and heat sources.
Load does not switch off, or switches on unexpectedly
• Ensure the set period is allowed to elapse with no motion in the detection zone.
• Ensure the unit is sited away from strong light and heat sources, including the load.
• Ensure there are no other inadvertent sources of triggering. To test this, tape thick
paper or card over the sensor lens (and wait for the set timeout period to elapse).
